What is the formula for calculation acceleration??

• Acceleration = Distance / Time

• Acceleration = V^f - Vⁱ / Time

• Acceleration = V^{i - Vf / Time}

• Acceleration = Time / Velocity

What does the term centripetal acceleration mean??

• an object traveling in a circular pattern

• an object that is speeding up quickly

• an object that has reached its maximum speed

• an object that is heading to earth

When calculating the net force of an object in which the forces are working in the same direction, you __ the forces.

• subtract

• multiply

• divide

• add

Balanced forces __.

• Always cause an object to move

• Always cause an object to stop

• Never cause an object to change its current state of movement or rest

• Often cause an object to speed up

An object with a net force that is NOT equal to zero __.

• experiences balanced forces

• must be at the rest position (unmoving)

• experienced unbalanced forces

• must be moving quickly
